NAPOLEON Dll' BRUL, OF CINClINNATI, OI-IIO, ASSIGNOR TO THE MILLERDU BRUL & PETERS MANUFACTURING (10., 0F CINCINNATI, OHIO, A CORPORATION OF OHIO.

CIGAR-MOLD.

To all whom it may concern:

Be it known that I, NAPOLEON DU BRUL, a citizen of the United States of America, residing at Cincinnati, in the county of Hamilton, State of Ohio, have invented cer tam new and useful Improvements 1n Cigar-Molds, of which the following is a specification.

The object of my invention is to enable the user of cigar molds to avoid applying the lid ofthe mold in reversed position and thereby bringing the point ends of the cups over the tuck ends of the cavities with resultant dzunage to both the mold and its contents.

In the manufacture of cigars by hand, the cigar bunches are placedin the molds and the lid is placed on the bottom of the IIIOlCLiLftGI' which the mold is subjected to pressurein a suitable press provided for the purpose -in some factories a hand press and in others a hydraulic or powerful screw press operated by power and inwhich many molds may be introduced for pressing at one time. The molds :are carried to the press by the pressmen, who generally do not eX- amine the molds to ascertain whether or not the lids are on right before the pressing is done. Hence, if the lid has been incorrectly placed, that is to say if it has been appliedwith the point ends of the cups over the tuck ends of the cavities, the sharp edges of the cups not only become damaged themselves, but cut intoand ruin both the walls of the cavities and the cigar bunches contained therein, thus causing a double loss.

f Many expedients have been, resorted to, to prevent the reversal of the lid, such for instance as placing two guiding dowel pins on the under side and at one end of the lid, and one dowel pin on the under side and at the other end of the lid. Again manufacturers have placed a single dowel pin at each end of the lid on the under side, out of alinement with each other and of different diameters. one end and a block at the other, and various other devices for the same purpose, but each expedient has been found to be objectionable or has failed to overcome the difficulty. v i a All guiding devices of this character, so far as. I am aware, have been placed on:the under side of the lid and are, therefore, concealed. from the operator whenever the lid Specification of Letters Patent. 1

Again they have used pins at is right side up, and particularly when he is placing the lid on the mold. Hence there is no visible meansof either insuring proper assembly or determining whether or not the lid is in proper relation to the bottom mem her, after the members are assembled, and the cigar manufacturer is apprised of the improper assembly of the mold only after it has been removed from the press and opened to disclose destruction to both the mold and its contents.

My invention consists in providing a cigar mold with a guide for the assembly of its two members upon which the cups and cavities are mounted, which guide shall so enter into the structure of the mold and lend such distinguishing character to the form of both members of the mold, that the guide shall be appreciable on either member through both the senses of sight and touch, whether the member be inverted or not, andwhether the members shall be assembled or separated, and such guide shall, by the relation of its parts on the respective mold members, immediately indicate how the members are to be assembled and after assembling stand as a continuing indicator as to whether thev are properly assembled, so thatnot only may the bunch maker properly apply the lid without delay incident to turning and ex-. amining the lid, but the pressmen may detect at a glance any carelessness on the part of the bunch maker in placing the lid.

In: the drawings :--Figure 1 is a detail perspective view of the bottom of the mold showingthe damage to the cups due to a reversal of the lid; Fig. 2 is a similar view of the top of the mold; Figs. 3 and 4 are views showing the preferred embodiment. of the new corner construction, Fig. 3 being a perspective view showing themold with the parts about to be assembled; and Fig. 4 being a detail perspective view showing the top member of the mold in inverted position which it usually assumes to protect its cup from injury when separated from the bottom. member. v

Figs. 1 and 2 are accurate drawings, respectively, of the bottom and top members of a cigar mold damaged by the reversal of the lid. The showing in these figures is a correct illustration of the average mold and not of an isolated case. In Fig. 1 it will be seen that the side walls of the cigar bunch cavities are split and slivered at a by the Patented Nov. 24, 1914s. Application filed April 9, 1914. Serial 830,694.

sharp edges of the cups on the lid, while the edges of the cups on the lid are notched at b, when the mold is pressed in the press.

The reference numeral 1 designates the bottom of the mold, 2 the cavities formed therein adapted to receive the cigar bunches. T he top 3 of the mold is provided with cups -:'r the walls of which are very thin. The mold members are held, when assembled, against relative movement by means of the dowel pins 5.

The structure thus far described is old and well known in the art.

In order to eliminate the liability of incorrectly assembling the mold parts, I cut adjacent corners of the bottom and lid preferably as shown at 00 a, in Figs. 3 and 4, on an obtuse angle or give them some equivalent corner-configuration extending through both members contrasting with that of the remaining corners which serves as a guide, which is always in sight on either member and which will, therefore, insure correct assembling of the parts. I find, from experience, that the workman becomes so accustomed to the cut off corner guide, that it prevents him from reversing the lid on the bottom of the mold, and thereby eliminates breakage and ruin of the mold and cigar bunc This guidenot only has an effect upon the eye of the workman but it is recognized through the sense of touch by the workman when he lifts the mold as it is the custom to grasp the mold at the ends, and if the lid is reversed, the ends will not match and this fact will be communicated to the workman assoon as his hand closes over the end of the mold, and even should the error be not recognized at the time of placing the lid, the protruding portion of one mold member associated with the cut-away portion of the other, would promptly attract attention. In this way the error will be detected before the mold is placed in the press.

By constructing a cigar mold witlna structural guide extending over adjacent external portions of the two mold members and, therefore, embodying registering guide sections carried by the respective mold members, and by having this guide of such nature that its two parts can be observed when the top is off and to one side, or when the top is being put in position and also when wholly assembled with thebottom, the workman mayreadily apply the top in correct position when closing the mold, or de-- tect carelessness after it has been improperly closed, and thus avoid the destruction and waste so commonly experienced with molds as heretofore constructed. Bymaking the Copies of this patent may be obtained for registry when the and that signify the members when separated as well as as sembled.

In presence ,ofr spective mold members, and contrasting with other similar parts of the mold, the

correct manipulation of the top or lid may be determined by the sense of touch and the eyes of the workman are thus left free for observing other features of the work so that the proceeding is correspondingly facilitated.

In using the old styles of mold with an interior guide it becomes necessary for the workman to turn the lid over and look at the shape of the cup to determine which way the cover must be put on to properly register with the cigar bunch member.

My invention provides a very cheap, simple and effective means to avoid losses incident to the damage to the'molds and cigar bunches caused by the reversing of the lid of the mold.

I claim 1. As anew article of manufacture, a two-part cigar mold comprising top and bottom members carrying the shaped molding cups and cavities; said mold-members having adjacent corners cut-away to give them configurations which conform with each other but contrast with the other corners of the mold, and thereby provide an external structural assembling guide embodying registering guide sections that are adjacent when the moldmembers are correctly assembled, and presented in position to signify the relative positions of the mold members when separated as well as when assembled. v

'2. As a new article of manufacture, a plinth-like cigar mold, comprising top and bottom members carrying the cups and cavities for shaping cigar bunches; said mold being provided with an externalstructural assembling guide; said guide comprising cup on the lowerfaces formed in a diagonal plane intersecting both mold-members at one corner of the mold, and thereby forming indexes that convform with each other and contrast with the remaining corners of the mold. members and are appreciable through both vision and touch andin positions that bring them into members are assembled,
